Brite day, I love the way you think. I have been giving my chickie chicks warm oatmeal with yogurt, almond butter I got on sale and raw pumpkin seeds for treats. Also scratch and seed. But I swear the girls legs look skinny. The leghorns seem smaller. They have an option of where to be here in north georgia. Either in their nesting/roosting room which is lined and has a heatlamp which comes on when the temps drop below 35. And I keep their laying pellets and water in there, cuz water wont freeze there. Or they can be out in the big covered pen where we keep the pen lined with bales of straw two high to keep the wind from whipping through. It is fabulous. But I too want to give my chickies more protein and try to fatten up to make their first winter better for them.
